To all rwhom. it may concern:

.Be it knownthat I, ToNJEs AUGUST CARL BOTH, a cit-izen of the United States, and a resident -of .New York, in. the county of New York and State of New York, have invented certain vnew and useful Improvements in Mechanical Movements, of which v This invention relates to mechanical .movements adaptedl for universal application andis an improvement upon U. S. Patentv #943,274, patented December 14, 1909,

and is a division of my copending application Ser. No.'570,`138.

I have shown my mechanical movement located in an' electric light socket and adapted to make and break the current therein, though -it is to be distinctly understood that my invention isl not lto be i limited to this or any other particular use.

My invention further relates to an electric light socket in which my improved mechanical movement is used, fall of which will be hereinafter described -in the specication and pointed out in the claims.

In the/.accompanying drawings showing an illustrative embodiment of my invention and in which the same reference numerals referto. .similar parts in the several ligues-Figure.l 1 is a vertical section through an electric light socket equippedv with my invention, a part of the ligure being shown in side elevation for the purpose of better==-illustration;.Fig 2 is a vertical section through my mechanical movementand the electric light socket on which `it is mounted; Fig. 3 is a longitudinal section substantially on v the line 3-3 ofl Fig. 2; Fig. 4 is a vertical section substantially on the line i-#tof Fig. 3; Fig. 5 is a vertical section substantially on the line 5--5 of, Fig. 3; Fig. 6 is a detail end view showing the arrangement of the driven member and the laterally movable contact. plates; Fig. 7. is a vdetail perspective' viewl o f one form of laterally movable conducting or bridge plate; Fig. 8 is a detail side elevation of a center contact; and Fig. 9 is a detail per-.-

spective view of one form of tuated plate. In the illustrative embodiments ofthe inspring ac- .vention shown in thedrawiigal is an eleci tric' light socket having the usual or any approved outer shell 2, a cap y3 and with any form of insulation .4 between the 4shell and the screw shell contact, Fig. 1. The insulation which is-usually used to line the v cap 3 may be employed, if desired, but' preferably is omitted.' The shell, cap and insulation form no part of my invention and therefore willV be disregarded in the further description of the invention.

To house and thoroughly protect my'mechanical movement, when it is used as the operating switch mechanism in an electric light socket, I mount it in the interiorG of a hollow insulating receptacle 7 usually formed of porcelain or some other suitable material. The insulating receptacle 7, of porcelain, orother ,suitable material, is entirely closed except the bottom which is closed by the top 8 of the screw shell contact 5, an interposed insulating disk 10 being preferably employed. This-screw shell contact 5 and the interposed insulating disk 10 are held to the insulating receptacle' 7 by any suitablemeans such as by the screws 11, ll'and nuts 12, 12, Fig. 4.-. In this Iform of my invention, the driven member 13 is splined or otherwise properly secured upon the driving member 14 as in my said ycepending application, and is formed of porcelain or other suitable insulating material and' is provided at one end with a circumferential groove 15, Fig. 3.- Loosely mounted within the circumferential groove v15 an .rated from each other are two conducting bridge plates 16 and 17, respectively, which are alike but coperate with diiferent contacts. construction, one of them being shown in Fig. 7 in perspective. They each consist essentially oftwo connected U-shaped members having a connecting portion 18, which 'is preferably formed concave on its edge 19, its surface forming a segment of a circle These bridge pieces are of peculiarA sepawhose diameter is greater than that of the drivingmember 14:. On' each end of the bridgev plates 16 and.1 7 arespring jaws 20, 20 Vwhich yieldingly engage the lixed contacts to be hereinafter described.

. In the insulating disklQ I 'prefe'rably provide recesses or guideways v21, 21 within which slide the parallel projections 22, 22 l ofthe bridge- 'plate 17. The similar projec- 'tons 23, 23 on ,plate y1t are guided in grooves v24,24 formed in the head 25 of the one piece insulating receptacle 7. From this manner of loosely mounting the bridge pieces 16 and- 17 in the circumferential .groove it will readily be seenthat they move with the driven member 15, but they are not rotated. as the driving and driven members are given a partial revolution in i, eitherI direction to actuate the driven memstantially inverted L-shaped member 26 hav lng a forwardly extending contact 27 and a foot 28, one end 29 of which contacts with the center contact of the lamp or other consuming device (not shown), the other end `of the foot being enlarged at 30 and apertured at 31 for the reception of some proper securing mechanism such as a screw 32 which takes in to the threaded aperture 31, Figs. 2 and 8. Il also connect a contact 132 to the screw shell 5 having it extend up into the opening inthe receptacle 7 and locate it op'- posite a terminal contact 33, Fig. 5, which is connected with a binding post 34, Fig.

On the driven member 13 I form opposed incline surfaces forming hills 36 and valleys 35, as in my said copending application. To coperate with .the hills 36 and valleys 35 on the driven member 13 lI arrange one or two spring pressed plates 37 Aand 38, each being operated by springs 39I and 40, respectively, the former, preferably though not necessarily, resting in a recess 41 in the head 25 of the insulating receptacle 7 and' the other spring 40 resting upon thefinsulating disk 10. From the mechanism .previously de`V scribed it is clear that upon the partial revolution of the driying member 14 96 degrees, in either direction the driven'member '13 will be also caused to rotate with the driving member. This will cause the spring pressed vplates 37, 38 to be forced apart and thereby store up energy in the springs 39 and 40 until7 what is tegmed in this specification a hill is brought into contact with the plates 37 and '38 when 4the energy in the springs 39 and 40 will then exert itself to cause the yplates 37 and 38 to move down the incline surfaces into the opposed valleys. This, as previously described, willfcause a quick snap of the driven member in the opposite direction, either tounake or break the current as the case may be.

Y To prevent the plates 37 and 33 moving Vdown their respective cooperating incline surfaces, I provide any suitable means to. .lock them from such movement until. the

springs' 39 and40 have been compressed to their maximum degree upon the complete.

partial' revolution of the driven member 13, p

lserrata A cheap and economical locking means are the locking notches 142 142 `which hold the plates, in whichever way the driven mem ber is rotated, until the maximum. energy is stored up in the springs 39 and 40. 'The plates being then released cause the driven member 13 to move laterally with a quick and positive snap either to make or break the electrical connections.

In the present construction the partial ro-V tation of the driving member 14 and the driven member 13 will not aifect the conducting bridge plates 16, 17 vwhich are loosely 'mounted in the circumferential groove 15.

The longitudinal movement of the ,driven member, however, controls and actuates both bridge o'r contact pieces 16, 17 to move them to or from their coperating contacts to make a double pole quick make and quick 'break electric light socket. If the positive wire is connected to the binding post 42`- by vway of example, the current will pass into the contact 43 connected to that post, then through the bridge piece 16 over to thereontact 27 carried'by the center contact 26, thence through the foot of that Contact 29, through the lamp or other consuming device, thence to the screw shell contact 5, contact 132, Fig. 5, bridge piece 17, Contact 33 to the corresponding negative binding post 34.

vTo break the contacts the driving and driven members are given a partial rotation of degrees in either direction, as piviously described, which, however, will not rotate the bridge pieces 16 or 17, when the spring plates 37 and 33 will cause the driven member 13 to give a quick snap longitudinally of the drivingl member 14 and carry Awith itboth. plates 16 and 17, thereby making a quick break between each plate 16 and 17Mand their respective coperating contacts.- A. further rotation of 90 degrees in either direct-ion will reverse the movement yof the bridge pieces 16, 17 in a'manner previously described, and cause them to snap back and make a quick 'make with their respective cooperating contacts. I, therefore, in this construction have also both a double pole quick makeand tected inthe one pieceinsulating receptacle, though of course,- it is to be'understood that as a mechanical movement my invention is not to be confined to this or anyother par#4 'with a locking plate45 which is dropped into a slot 46 in the receptacle 7, a piece of insulation 47 bein-g preferably interposed between it and the centervcontact -26 as clearly shown in Fig. 2.
